This will be an interesting thread. The J30 (as well as the J24) has been notorious for weak light air performance. I don't know what boats the J30 is being compared too since I usually kick butt in light air, pointing or not. The light air performance is the reason for the 163% genoa and oversized chute.

Stick with the basics: In really light wind, flatten the sails and add twist. The wind will be stronger higher off the water and therefore farther aft, hence the twist in the sails. Put your crew to leeward and forward to induce a little weather helm. Foot more and keep your head out of the boat (look for more pressure). Downwind get the weight out of the back of the boat to lift the stern up and reduce wetted surface. Consider going with the class spinnaker. The current theory is that the extra sail area is worth the penalty. Sail higher angles to keep pressure in the sail.

Maybe somebody with connections will realize this thread belongs in the Racing section. Might get more of a response with the right visibility.
